@brief Select all vertices targeted by the edges selected before.

graph_query.toVertices(examples)

Creates an AQL statement to select the set of vertices where the edges selected in the step before end in. This includes all vertices contained in _to attribute of the edges. The resulting set of vertices can be filtered by defining one or more examples.

@PARAMS

@PARAM{examples, object, optional} See Definition of examples

@EXAMPLES

To request unfiltered target vertices:

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLToVerticesUnfiltered} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); var query = graph._edges({type: "married"}); query.toVertices().toArray(); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT

To request filtered target vertices by a single example:

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLToVerticesFilteredSingle} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); var query = graph._edges({type: "married"}); query.toVertices({name: "Bob"}).toArray(); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT

To request filtered target vertices by multiple examples:

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphFluentAQLToVerticesFilteredMultiple} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("social"); var query = graph._edges({type: "married"}); query.toVertices([{name: "Bob"}, {name: "Diana"}]).toArray(); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT
